A new multiyear study reveals wheat disease losses totaling $2.9 billion in the US and Canada between 2018 and 2021. The top three yield-reducing pathogens were fusarium head blight, stripe rust, and leaf rust.
Researchers uncover a novel immune mechanism by which wheat tandem kinase proteins (TKPs) combat pathogen invasion, establishing a new paradigm for cooperation between TKPs and NLR proteins. The discovery offers a foundation for engineering crop varieties with broad-spectrum pathogen resistance.
A new study published in Science reveals the first molecular events that give wheat immunity against stem rust, a major wheat disease. The findings provide insights into how to engineer wheat with stronger resistance against infection.
A comprehensive set of genomic resources for Tausch's goatgrass has been established, shedding light on the evolutionary genetics of wheat. Researchers identified a stem rust resistance gene and a leaf rust resistance gene, which will aid in breeding more resilient wheat varieties.
Experts warn that fungal disease in crops could lead to unprecedented challenges in food production, causing losses equivalent to enough food for millions of people. The increasing prevalence of fungal infections is due to rising temperatures and the development of resistance to antifungals.
Researchers at King Abdullah University of Science & Technology (KAUST) have identified a stem rust resistance gene in Aegilops sharonensis and transferred it to common wheat. The new transgenic wheat lines show high levels of resistance to the stem rust pathogen, providing hope for mitigating the devastating effects of climate change.
A team of researchers identified a stem rust resistance gene from wild goat grass species Aegilops sharonensis, which can be cross-bred into wheat for immunity against deadly crop pathogens. The genetic potential of this hardy relative has been largely unexplored and holds promise for reducing the threat of the stem rust disease.
Researchers at the University of Minnesota have identified a gene, Rpg7, responsible for high stem rust resistance in wild barley from Jordan. This discovery could provide valuable insights into breeding programs to combat this devastating disease affecting global cereal crops.
A new study finds the Sr22 gene is conserved among grasses in the Triticeae and Poeae lineages, with significant expansion in barley and oat lineages. The research provides valuable insights into plant disease resistance gene function and evolution, potentially improving crop resilience to agriculturally important diseases.
Researchers analyzed the genome of Ug99 and found that it emerged as a result of somatic hybridization between two different rust strains, creating a unique hybrid with increased virulence. This discovery provides new insights into how Ug99 was able to threaten wheat crops across the world.
A new study has reported the first case of stem rust in wheat in the UK in over 60 years, warning of a perfect storm of conditions favourable to its resurgence. The fungus is susceptible to over 80% of UK wheat varieties, and its spread could be exacerbated by climate change and Barberry planting.
Researchers have gained crucial gene-level insights into an age-old evolutionary arms race between wheat and stem rust disease, a devastating fungal pathogen. The studies identified key peptides released by the fungus that can evade plant immune systems, potentially allowing for more effective DNA testing to identify resistant crops.
Researchers at Kansas State University have identified a key component of plants' immune system that recognizes and fights the invasive Ug99 stem rust pathogen. The discovery of the Sr35 gene provides hope for developing new wheat varieties to protect global food crops against this devastating disease.
The Rust-Tracker system can monitor 42 million hectares of wheat in 27 developing countries and track the spread of stem rust and related strains. Experts warn that North Africa, Central Asia, and other regions are still vulnerable to the deadly disease.
USDA researchers have identified over 3,000 stem rust-resistant wheat landraces and are retesting them to verify their resistance. These landraces hold the key to combating severe losses due to stem rust, a disease affecting worldwide wheat cultivation areas.
Researchers at Washington State University have discovered how a barley plant recognizes an invader within five minutes of an attack, triggering its defenses. This breakthrough could lead to new ways to battle crop diseases, potentially defeating evolving threats like Ug99.
Researchers are close to producing super varieties of wheat that will resist the deadly Ug99 pathogen, while boosting yields by as much as 15 percent. The new varieties have genetic resistance to rusts, including stem rust, yellow rust, and leaf rust, which has infected up to 90% of global wheat production.
A global project led by Cornell University aims to identify new stem rust resistant genes in wheat, improve surveillance, and distribute rust-resistant wheat seed to farmers. The $40 million grant will support efforts to combat deadly strains of Ug99, a pathogen posing a significant threat to global food security.
The discovery of four new mutations of Ug99 stem rust poses a significant threat to global wheat production and food security. The new variants have acquired the ability to defeat two of the most important stem rust-resistant genes, making existing breeding programs less effective.
A new study by Oregon State University and other institutions reveals that invading diseases can accelerate their spread, posing serious concerns for human diseases and a new fungus threatening global wheat production. The research suggests that the right set of conditions could lead to significant crop losses in some parts of the world.
Scientists report significant progress in developing new wheat varieties resistant to virulent stem rust Ug99, which threatens global wheat production. The mutated fungus is on the march towards South Asia, where poor subsistence growers produce a significant portion of the world's wheat.
A new form of stem rust, Ug99, has jumped from eastern Africa to Yemen, infecting wheat in the Arabian Peninsula and spreading rapidly. The disease is predicted to reach vast wheat-growing areas of North Africa, the Middle East, Pakistan, and India.
